v3.5.0

[3.5.0] - 2019-01-04

Updated

• Updated Plotly.js to version 1.43.1. See the
  plotly.js CHANGELOG
  for more information.

Changed

• Plotly.js 1.43 converted title properties (e.g. layout.title) from
  strings into compound objects that contain the text as the text property
  along with new title placement attributes x, y, xref, yref, xanchor,
  yanchor and pad. Plotly.py 3.5.0 follows the new schema, but still
  supports specifying title as a string, in which case the string is assigned
  to the title.text property
  (#1302)
• Plotly.js 1.43 also moved existing title* properties
  (e.g. layout.titlefont) under the title object (e.g. layout.title.font).
  Plotly.py 3.5.0 follows the new schema, but still
  supports the legacy title* properties by mapping them to the corresponding
  title.* property
  (#1302)
• The update method on graph_objs now returns the updated object in order
  to support chaining multiple update operations together
  (#1379)
• The show_link option has been set to False by default in the offline
  plot and iplot functions. Now that the "send data to cloud" button has
  been disabled by default in plotly.js 1.43.0, no buttons/links will be
  displayed by default that result in data being sent off of the local machine
  (#1304)
• config options that are not known by plotly.py result in a warning but are
  still passed along to plotly.js. Prior to this change these unknown options
  were dropped silently
  (#1290)
• Built-in themes now specify colorscales using the new global
  layout.colorscale properties. Previously the colorscales were defined for
  each trace type individually. This reduces the size of the resulting theme
  files
  (#1303)
• Increased the maximum retry time of the orca integration from 8s to 30s
  (#1297)

Fixed

• Fixed FigureWidget performance regression that, when working with
  large datasets, resulted in a slight freeze of the widget after user
  interactions (pan, zoom, etc)
  (1305)
• Fix orca error when the ELECTRON_RUN_AS_NODE environment variable is set
  (#1293)
• The 'responsive' config key was being silently blocked
  (#1290)
• Fixed error when using unicode characters in string properties on Python 2
  (#1289)
• Removed invalid calls to non-existent validate and strip_style Figure
  methods in matplotlylib conversion logic
  (#1128)
